It's the old aluminium mac mini. It has DVI port at the back, 1GB DDR2 667MHz SDRAM and a 1.83GHz Intel Core 2 Duo. The 1GB RAM is a little sluggish - I'd like to upgrade it. Can I take it into an Apple store and get them to do it? If so, how much does it cost for them to take it up to 2GB? If they won't do it is there specific mac RAM I need to buy for it if I want to do it myself?
